    In this study, a model for evacuation destination recognized by a resident in a post-earthquake fire event was developed considering attractiveness of a post-earthquake fire refuge. When a large earthquake hits a city in Japan, a tremendous number of evacuees may wander around in urban area escaping from hazards due to conflagrations following the earthquake. We have been developing a simulation model for city evacuation of residents in post-earthquake fire as a tool to evaluate effectiveness of evacuation safety measures. For the further refinement, it is important to accurately estimate evacuation destination of residents considering bias of attractiveness of refuges. The interview survey was carried out at 104 spots on busy streets in Kyoto City and replies from 2,267 residents were collected from September 1st to November 30th, 2009. In the interview, the names of open-spaces recognized as evacuation destination were asked having the subjects imagine that conflagrations had taken place in urban area. The governing factors of evacuation destination choice were identified by analyzing the survey data. Then evacuation destination of a resident was formulated by adopting a probabilistic model and validated by using the survey data. Finally, the model was applied to the whole area of Kyoto City and the number of residents evacuated to a post-earthquake fire refuge was estimated.
